| 摘 要： | 建议了一个非常简化的不同级别河流沿岸的各个港口之间的贸易和经济发展的模型，希望得到健康贸易网络的机制。模型包含有走向均衡和两极分化这两种互相矛盾的发展机制。数值模拟结果说明，在总财富守恒或不守恒的条件下，这两种机制会达到相对说来不健康或者健康的经济发展图像。对于吞吐量的分布的模拟结果，在两种情况下都基本与实际统计结果定性一致。

| Abstract: | A simplified model for simulating the trade activities and economic development of the open ports along the rivers of different grade is suggested.We hope to get a mechanism of the trade networks.The model includes two developing mechanisms: leading to equilibrium or to polarization.Our simulation results suggest that they can induce healthy on un-healthy pictures of economic development in different conditions where the total fortune are not conserved or conserved.In both the cases the cumulative distribution of the year's throughput of the open port's,which is obtained by a numerical simulation based on the model,shows power distributions,in a good agreement with the practical empirical results. |
